The authors of the article published recently in the European Respiratory Journal on the prevalence and correlates of airflow obstruction in >317 000 never-smoking Chinese subjects concluded that they found inconsistent associations with exposures to household air pollution and went on to outline what future work needed to be done [1].

متن کاملDefining airflow obstruction.
Using a very large number of predominantly Chinese nonsmoking females aged 30–79 years, SMITH et al. [1] studied the relationship between airflow obstruction, household air pollution, household income, educational level and prior tuberculosis. They defined airflow obstruction as a ratio of forced expiratory volume in 1 s (FEV1) to forced vital capacity (FVC) of <0.7 or <5th percentile, and grad...
متن کاملAsthma and irreversible airflow obstruction.
To determine whether asthma alone can cause irreversible airflow obstruction 42 men and 47 women with chronic asthma (mean duration 22 (SD 13) years) without evidence of other disease likely to cause irreversible airflow obstruction were treated with theophylline orally and a beta agonist both orally and by inhalation for four weeks. After two weeks of treatment the FEV1 was less than 85% of th...
متن کاملAspects of chronic airflow obstruction.
This report questions several commonly used definitions and commonly accepted concepts. It suggest that the term, "chronic airflow obstructions," should replace the terms, "chronic obstructive pulmonary disease," "chronic obstructive lung disease," or "chronic airway obstruction," because it is flow that is obstructed. It is suggested the term, "chronic mucous hypersecretion," be used, rather t...
متن کاملModerately severe chronic airflow obstruction. Can corticosteroids slow down obstruction?
In a former study in patients with severe chronic airflow obstruction (CAO), (forced expiratory volume in one second (FEV1) ranging from 350-910 ml), we concluded that daily oral corticosteroids might slow down the progression of disease. The results of the present long-term (14-20 yr) study on 139 non-allergic patients with less severe CAO (FEV1 greater than or equal to 1200 ml, FEV1 as a perc...
